SWM

I got into vintage trials a few years ago, I always wanted a SWM! When I was a kid SWM trials where the bike to have! I didn't have one then but almost 40 years later I finally bought one! I really like them! They handle great and the brakes even work! I enjoy them as much as the modern trials bikes I had! I actually ended up with four over the summer, (sold the 240 to a friend of mine). I have a 1980 TL320 that's my main bike, I bought from the top rider from our club, he also won the AMA National twin shock series in 2013 on the same bike! I also have a 1982 TL 320 practice bike that runs good but needs work and a 1980/81 TL 320 that needs rebuilding. I'm wonderi…

Now that my SWM is running reasonably well (still needs cosmetics) I have noticed, or imagined, that it does not pick up a quickly as my Aprilia did, is this entirely down to flywheel weight ? I suppose the sensible thing would be to take them off and weight them, but if some one knows ? Were there any other differences between the two Rotax engines, apart from clutch covers on the later Aprilia's ? Thanks Ross

Hi Guys, A very helpful past owner of my 1982 tl 320 let me know how he set the clutch up. As follows: replaced clutch springs with 6 xr 650 valve springs A$35.00, whacked on a venhill clutch cable and uses a magura lever rather than standard It works like a ty now, its great. I believe the plates were replaced with barnetts but still confirming that.

Question for any of you SWM owners whose bikes have a nice light clutch action - How do you set up the clutch spring tension? Are the pressure plate bolts tightened right up to the end of their travel and left like that or are they then backed off so many turns. Bike in question is a Jumbo which has the lightener under the tank connected up but the clutch action on the lever is very heavy - the pressure plate bolts are screwed all the way in so I'm wondering if they should be backed off a little but as I have no manual or set up info I've no idea. I can experiment obviously but if someone knows how they should be set it would make life easier than trial and error. Alt…

Has anyone tried removing the perforated tube inside the midbox to make it more like an expansion chamber? With the perforated tube in place it seems that the midbox is really just a muffler. A straight section of pipe would have virtually the same effect performance wise it would seem ,although the exhaust note would be a bit louder(but the bike 2.4lbs.lighter). I am considering combining a gutted midbox and a MX type rear silencer or custom aluminum replica SWM rear box to improve power( and save about 5lbs). I am familiar with making changes to the exhaust systems on piston port engines , but less informed on rotory valve engines, so I am not really sure if this would …

My SWM TL320 1982 has had a few updates so heres a few notes for others that maybe doing similar. New tyres michelin front; IRC rear, new wheel and str. head brgs., new chain and sprockets, new EBC brake shoes, fuel tap, new rear guard and new stickers. Heres a list on some of the work to date. 1. Stg. head brgs. not available in Oz [supplied from Martin at SWM moto]. 2. The sprocket I had on the rear had a steel insert /hub which offset the sprocket from the hub approx. 2mm. When I replaced with talon sprocket without a recess I used 2mm thick washers and ground them on one side so the chain wouldn't foul on them. 3. Sprocket bolts were loose when i went to change…

Here's my Jumbo project. I bought it as an unfinished project. It's slowly coming together. The tank was as knackered as you'd expect of a 30 year old bike, found a guy who polishes them up and he did a fantastic job, Now I need to make up some badges. Thinking of doing it in CAD and having them printed. If any one could provide straight on pictures of the right and left badges I'd much appreciate it. I'm happy to share the CAD file when done to anyone interested

Hi, has anybody out there had problems with Venhill cables ? I ordered clutch, throttle and frontbrake cables for my 81 125 and 320 and have had the following problems. The brake cables were too short and could not be fitted to the bikes any way even though the cables listed were for Marzocchi forks. The throttle cables fit as long as you only connect one end. The inner is too short or the outer too long on both, whichever way you look at it. The brake cable issue has been solved. Venhill changed them, no problem but now I'm trying to get the throttle cable problem solved. The picture shows the throttle end with the carb end in place. Even when all of the…

Hi, has anybody out there had any experience with this type of clutch actuator ? Does it make a big difference or none at all to the lightness of the clutch ?

Can you name all of the former SWM employees in the photo, taken recently at the Mont Ventoux Trial in France.

Has anyone tried a OKO carb on there SWM 320? If so how did it work?

over the last couple of months I've been getting through condensers rather too quickly, initially on my 320TL and now on the Jumbo. So done some investigative work and written it on my (mainly SWM) blogging website. SWM electrics I've basically not found the problem, but tried to eliminate the likely suspects, we shall see....

Hi all new here kinda. Short version I have ridden trials since 71 and still have a vintage trials OSSA MAR 250 and vintage enduro bikes, modern enduro bike and modern trials Beta Rev. In 1980 I bought a new 320 TL, rode for several years, left for a year in OZ and sold bike to a friend. Came back he had sold it and I could not find it again....wanted it back. After a few years gave up. Bike turned up on monday on e-bay, Vinduro group mentioned it....someone was looking for a SWM enduro, this was a trials bike. But it was just 15 mins from me so I clicked on the link. Wow looked like my old bike, more I looked at it more it looked like it. About 12 hours left on the aucti…

This all wheel drive SWM was built in 1981! It was a Prototype, they competed with it once and the FIM banned all wheel drive bikes. If anyone else knows anymore about this Prototype or have more pictures, please post them!

Hi All, I'm building a 350 Jumbo for competition and was wondering if anyone has matched the cases on the motor? Did it make a difference? If so what difference? Thanks

HI can anyone tell me where to position the disc valve in relation to TDC or BDC on a 1980 tl320. I cant see any marks on the engine and as I received the engine in several boxes I am in the dark. I think that the disc should start opening just as the crank goes past BDC but any advice would be appreciated. Thanks

Was at a trial yesterday and a very kind person gave me a tip. He said that if I turned the front brake arm so that it was pointing forwards that it would work better. He then tried to explain that if the top shoe grips before the bottom shoe the brake works better. All I want to know is he talking p***

Before as I purchased bike Steel swing arm and early plastic tank, waiting for a seat Stand to fit, a few bits to finish, genuine side panels to fit, just waiting for a rubber seat to be made now
